CHESTER D. ZUMWALT, OF CENTER, MISSOURI.

MAGAZINE-CHARGER FOR FIREARMS.

To all whom it may concern:

Be it known that I, CHESTER D. ZrnvrwAL'r, a citizen of the United States, residing at Center, in the county of Balls, State of Missouri, have invented certain new and useful Improvements in Magazine-Chargers for others skilled in the art to which it apper tains to make and use the same.

The object of the invention 1s to provide an improved construction of magazine cartridge feed for guns which will operate automatically to feed the cartridges successively to the magazine of the gun independent of gas pressureor recoil and which when associated with a gun will not interfere with the elevation of the latter.

IVith the above and other objects in view the invention consists in the details of con struction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointedout in the appended claim.

In describing the invention in detail refer ence will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which 7 Figure 1 is a side view of a magazine cartridge feed for guns constructed in accordance with-the invention; Fig. 2, an opposite side "iew of the magazine cartridge feed; Fig. 3, a section of a fragment of a magazine cartridge feed showing the position of the parts before the reinforcing spring is expanded to its limit; Fig. 4, a view similar to Fig. 3 showing the position of the parts after the reinforcing spring has reached the limit of its expansion and the feeding spring has entered the flexible portion of the tube, and Fig. 5, a 'detail perspective view of the magazine cartridge feed.

Referring to the drawing the improved magazine cartridge feed is indicated generally at F and is shown as comprising a coil tube 48 provided on its inner side'with a continuous slot 49. This tube has secured thereto'a frame 50 through the medium of which the feed is adapted to be attached to the gun. Disposed within the tube 48 is a feeding spring 51 which has. securedto its advance end a plunger 52 and to its rear end a plunger 53, the latter being provided with Specification of Letters Patent. Patented July 25, 1916.

' Application filed April 14, 1916. Serial No. 91,172.

a recess 54 registering with the slot 49 for a.

purpose that will presently appear. The

delivery end of the tube 48 has secured thereto a flexible section 55 which is adapted to be directly connected to the magazine of a related gun. Rotatably mounted on the frame 50 is a shaft 56 which has fixed thereon: a ratchet Wheel 57. Coiiperating with this ratchet wheel is a spring controlled pawl 58 mounted on the frame 50. The shaft 56 is adapted to be rotated through the medium of a suitable key 59. Encircling the shaft 56 and having one end secured thereto is a coil spring 60. The other end of this spring 60] carries a shoe 61 which extends into the slot 49 and also into the recess 54 of the plunger 53.

r In the operation of the feed the required cartridges are inserted in the tube 48 and the spring 60 wound up by rotation of the shaft 56. During this insertion of the cartridges the spring 51 is forced to the end of the tube 48 remote from the flexible section 55. The pawl 58 is then held released and the spring 60 will hold the spring 51 at maximum'compression during feeding until the plunger 53 reaches the end ofthe tube 48 adjacent the section 55. The spring 51 will then expand in the section 55 and complete the feeding of the cartridges. The handle 62 is utilized to move the foot 61 to starting position when the spring 60 is wound up.

What is claimed is A magazine charger comprising a coiled tubular member having a continuous slot on the inner side thereof, a frame attached to the coiled tubular member, a shaft rotatably mounted on the frame, a coiled spring encircling the shaft and having one end secured thereto, a foot on the other end of the coil spring projecting through said slot, a feeding spring within the tubular member, plungers connected to the advance and rear ends of the feeding spring, the plunger connected to the rear end of the feeding spring having a recess therein in which the foot is engaged, and means for locking the shaft against rotation in one direction during winding of the coil spring.

In testimony whereof, I in the presence of two witnesses.
